Thanks Jimmer (and Wario). What about the rifle? You don't need that one either?

Well you CAN keep it, but that gun (the Typewriter) gives headshots from quite a far distance. If you're playing on wii, which you probably are because of where you posted this, than you should be able to get good headshots. Just be cautious when aiming near the first 2 Monks when you first reach the castle, and be cautious when you're shooting at the metal belts that are restricting Ashley in the castle as well. However, if you'd rather play it safe, you can keep the rifle, but I beat the game twice with only the Typewriter, so It really is up to you.
